What if I'm having a blast doing the tasks no one wants to do that are in the backlog.

Bullshit. There are some dysfunctional exceptions, but higher pay usually correlates with more freedom, more responsibility and access to more resources. You may get frustrated in Big Tech, because nowadays, people like to have no bounds in their expectations, but try changing your big tech job for a job in the oil or insurance industry with half the pay, and you'll see that most of the time, you not getting a blast out of your 600k job is mostly your fault.
